PP plastic has the characteristics of low density, good chemical resistance, low price and excellent comprehensive performance. After functional modification, it is widely used in the field of household appliances.
PP plastic is polypropylene, a thermoplastic resin made by polymerization of propylene. Polypropylene is a non-toxic, odorless, tasteless milky white high crystalline polymer, the density is only 0. 90~0. 91g/cm³, is one of the lightest varieties of all plastics. It is particularly stable to water, and its water absorption rate in water is only 0. 01%, and its molecular weight is about 80, 000-150, 000. Formability is good, but because of the shrinkage rate is large (1%~2.5%), thick wall products are easy to sag, for some parts with higher dimensional accuracy, it is difficult to meet the requirements, and the surface gloss of the products is good. The copolymer type PP plastic has a lower thermal deformation temperature (100℃), low transparency, low gloss, low rigidity, but has a stronger impact strength. The Vicat softening temperature of PP plastic is 150 ° C. Due to the high crystallinity, the surface stiffness and scratch resistance of this material are excellent. PP plastic does not have the problem of environmental stress cracking.
PP plastic through modification, can be made into high-gloss PP, heat resistant PP, high impact resistant PP, enhanced PP, antibacterial PP, antistatic PP, anti-dyeing PP, weather-resistant PP, halogen-free flame retardant PP, environmentally friendly flame retardant PP, non-filled PP, according to the functional classification, can be anti-cockroach anti-bite PP, easy to clean PP, etc. Different functional properties of modified PP materials, in the specific application is not the same.
Anti-cockroach, anti-rodent bite PP plastic
Anti-cockroach and anti-rodent biting PP plastic can prevent the electrical hazards of cockroaches and rats by stimulating their taste and smell. Mainly used in electromagnetic stove and other electrical appliances.
Easy to clean modified PP plastic
Easy cleaning modified PP plastic is by introducing low surface active energy substances into traditional PP plastic, increasing the contact Angle between water and oil on the surface of the material, forming a super hydrophobic surface, and becoming a PP plastic with antifouling and easy cleaning ability. It is widely used in the appearance parts of kitchen appliances such as rice cookes. electric pressure cookes. induction cookes. microwave ovens, range hoods and so on. Improve the common PP plastic in the kitchen environment easy to dirty, cleaning difficulties and other problems.
High gloss PP plastic
High gloss PP material has excellent aesthetic effect and excellent appearance, mainly used in small mechanical and electrical shell, such as rice cooker, soy milk, mechanical and electrical kettle, washing machine, refrigerator, personal care, pressure cooker, induction cooker, dishwasher, air conditioner, iron and so on.
Anti-staining PP plastic
In order to reduce costs, the inner liner materials of household appliances such as dishwashers or juice machines are mostly produced by modified PP plastics. After repeated use, the inner liner is easy to show dirty. The reason is that the liner material is directly in contact with juice, food residue, food condiments and so on, which causes the surface color of the material to change. When the color changes to a certain extent, it will be dirty, and even contaminate the next batch of food as a pollution source, reducing the quality of the product. These problems can be solved by using anti-staining PP. Poly-cyeron anti-dyeing PP plastic has the characteristics of pollution, anti-dyeing, high fluidity, stiffness balance and so on. It is mainly used in spray arm pipe, filter screen and other dishwasher parts.
Antibacterial PP plastic
Household appliances such as washing machines, air conditioners, air purifiers, water purifiers, refrigerators and other household appliances can breed a large number of pathogenic bacteria and mold after a period of use, which poses a direct threat to the health of consumers. Antibacterial PP plastics can inhibit or kill bacteria, mold, alcohol bacteria, algae and even viruses that are contaminated on the plastic, and keep themselves clean by inhibiting the reproduction of microorganisms. Polycylon antibacterial plastic for household appliances has the characteristics of high strength, high toughness, and inhibition of bacterial mold growth.
Microfoaming modified PP plastic
Microfoaming modified PP plastic refers to the polypropylene material as the matrix, through the injection molding process under the action of gas pressure, so that the middle layer of the product is densely covered with the size from ten to tens of micmeters of closed micropores and both sides have a dense skin structure, so as to achieve the purpose of saving material and weight. Due to the lower stress used in the microfoaming modified PP plastic, the injection molding is smoother, straighter, and more stable in size. At the same time, due to the support of the micropores, the shrinkage marks of the parts can also be effectively solved.
Poly Cyelong company through the optimization of the formula design, precise processing technology, special screw combination and mixing technology to develop micro-foaming modified PP plastic, used in the field of lightweight.
Long glass fiber reinforced PP plastic
Long glass fiber reinforced PP plastic refers to the modified polypropylene composite material containing glass fiber length of 10 to 25mm. After injection molding and other processes to form a three-dimensional structure, it has higher comprehensive performance than ordinary glass fiber reinforced PP.
Long glass fiber reinforced PP can be used to make automotive parts, including bumpers, instrument panels, rear door baffles, front components, seat supports, noise partitions, battery brackets, shifter bottoms, bottom shields, sunroof sinks, etc.
Poly-celon long glass fiber reinforced PP plastic grades: PPLGF-30H, PPLGF-50H, PPLGF-40H
High glow wire PP plastic
The materials used in high-power appliances should have high glow wire performance, and high glow wire performance means that the product has safer performance. Poly Celon high glow hot wire PP plastic with high CTI, halogen free flame retardant characteristics, and through the UL yellow card certification, widely used in capacitors, storage box, power supply shell, fan shell, circuit board support, electromagnetic stove bottom cover plate and other electrical appliances.
Low odor PP plastic
Low odor PP plastic has the characteristics of balanced mechanical properties, excellent processing performance, high heat resistance and low odor, which is used in the field of automobile interior. In view of the environmental protection requirements of the car, Poly-Cylon has developed a special low-odor PP plastic for passenger car interior. The "Golden Nose" test team is a professional evaluation team with the qualification certificate of automotive Interior odor Evaluators issued by SGS. Polycylon automotive interior special low odor PP plastic odor less than 2.5.
Low-odor PP plastics are mainly used in the field of automotive interior, such as door panels and dashboard panels.
